Title:
DIMMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/006539
Kind Code:
A1
Abstract:
Provided is a dimming device compatible with more types of illumination loads. A signal source (910) generates a drive signal (Sd1) corresponding to a dimming level. A discharge part (920) includes a serial circuit that comprises a Zener diode (ZD1), and a rectifier element (D9) through which the reverse current of the Zener diode is passed. In the discharge part (920), the serial circuit is electrically connected between a control terminal (20) and the signal source (910) such that the reverse current of the Zener diode (ZD1) flows from the control terminal (20) to the signal source (910).
